Four‐ to Six‐Year‐Old Children's Sensitivity to Reliability Versus Consensus in the Endorsement of Object Labels
下载免费PDF全文

Recent studies have demonstrated that young children use past reliability and consensus to endorse object labels. Until now, no study has investigated how children weigh these two cues when they are in conflict. The two experiments reported here were designed to explore whether any initial preference for information provided by a consensual group would be influenced by the group's subsequent unreliability. The results show that 4‐ and 5‐year‐old children were more likely to endorse labels provided by an unreliable but consensual group than the labels provided by a reliable dissenter. Six‐year‐olds displayed the reverse pattern. The article concludes by discussing the methodological implications of the two experiments and the developmental trajectory regarding the way children weigh consensuality versus reliability. 相似文献

Collaborative information behavior is an essential aspect of organizational work; however, we have very limited understanding of this behavior. Most models of information behavior focus on the individual seeker of information. In this paper, we report the results from two empirical studies that investigate aspects of collaborative information behavior in organizational settings. From these studies, we found that collaborative information behavior differs from individual information behavior with respect to how individuals interact with each other, the complexity of the information need, and the role of information technology. There are specific triggers for transitioning from individual to collaborative information behavior, including lack of domain expertise. The information retrieval technologies used affect collaborative information behavior by acting as important supporting mechanisms. From these results and prior work, we develop a model of collaborative information behavior along the axes of participant behavior, situational elements, and contextual triggers. We also present characteristics of collaborative information system including search, chat, and sharing. We discuss implications for the design of collaborative information retrieval systems and directions for future work. 相似文献

This article investigates whether schools that match Coalition Government criteria for excellence can enable hardworking students, regardless of background, to achieve good examination results and improved chances of social mobility. Students at two case-study academies were interviewed about family influences on their development and choice of education and employment pathways. In a ‘best case’ scenario, where prototype academies have rigorously implemented government policy, are students less reliant than before on family resources, influences and dispositions? Our data suggest that family background continues to be an important influence on participants’ attitudes, values, occupational interests and preferences. There are few signs that the new academy regime is creating improved opportunities for social mobility. 相似文献

Online education has grown over the last ten years and with it has been an increase in diverse learners. In an effort to understand how online teachers meet the needs of diverse learners, researchers surveyed teachers in two cyber schools. 118 participants were asked their definition of differentiation and how differentiation is seen in their practice. After the survey was collected, NVivo qualitative software was used to continually reduce the data through constant comparison. The results from the survey data revealed that online teachers defined differentiation from two distinct perspectives: a) why a student needs differentiation, and b) what a student needs differentiated. Online teachers stated learning styles as their primary reason for differentiation. This result was not only different from findings in face-to-face classrooms, but does not support research on what impacts student achievement. Online teachers also cited when they differentiate, they adjust content, product, and process (63% coverage). Finally, noticeably absent from the data were references to using assessments in the classroom to inform differentiation. Future research should consider how online teachers differentiate in their learning environments and how they make day-to-day decisions as they adjust instruction to meet the needs of their learners. 相似文献

Employment opportunities for persons with doctoral degrees in counselor education and counseling psychology were studied. Over 15 months, 708 positions were identified and analyzed to determine frequency of advertised positions calling for either degree, types of positions, and references to the Council for Accreditation of Counseling and Related Educational Programs (CACREP) or the American Psychological Association. Additional analyses were conducted for counselor education. Results found the counselor education degree to have a clear identity in the marketplace, especially for faculty positions, whereas the degree in counseling psychology was more often 1 of multiple degrees listed for an advertised position. Implications are discussed, including implications for CACREP‐accredited doctoral programs and needs for future research. 相似文献
